Matrices and determinants Chapter #1 Pdf Download
The matrix determinant represents a number. We get this value by multiplying it and adding its elements in a certain way.
Real and Complex Numbers Chapter #2
A complex number is a combination of a real number and an imaginary number. A complex number is in the form of a + ib and is usually represented by z. Here a and b are both real numbers. The value ‘a’ is called the real part which is denoted by Re (z), and ‘b’ is called the imaginary part Im (z).
Logarithms Chapter #3
logarithm, the type or power to which a base must be asked to yield a given number. As stated mathematically, x is the logarithm of n to the base b if bx = n, in which case one writes x = logb n. For example, 23 = 8; therefore, 3 is the logarithm of 8 to base 2, or 3 = log2 8.
